Also this.

>>> import datetime
>>> d0 = datetime.datetime.strptime("2024-0-3 00:00:00", "%Y-%W-%w %H:%M:%S")
>>> d0.strftime("%Y-%W-%w %H:%M:%S")
'2024-01-3 00:00:00'
>>> d1 = datetime.datetime.strptime("2024-1-3 00:00:00", "%Y-%W-%w %H:%M:%S")
>>> d1.strftime("%Y-%W-%w %H:%M:%S")
'2024-01-3 00:00:00'
>>> d2301 = datetime.datetime.strptime("2023-0-1 00:00:00", "%Y-%W-%w %H:%M:%S")
>>> d2311 = datetime.datetime.strptime("2023-1-1 00:00:00", "%Y-%W-%w %H:%M:%S")
>>> d2301
datetime.datetime(2022, 12, 26, 0, 0)
>>> d2311
datetime.datetime(2023, 1, 2, 0, 0)
>>> d2311.strftime("%Y-%W-%w %H:%M:%S")
'2023-01-1 00:00:00'
>>> d2301.strftime("%Y-%W-%w %H:%M:%S")
'2022-52-1 00:00:00'


Week 0 2023 became Week 52 2022 (which is correct but might lead to surprises)
